With NBN, on weeknights, the local windows are longer, the first local news window is about 6 minutes long and (for most markets), there's 2 local reports, 1 "out of area" report, and 3 voiceover items (usually with footage), again probably one 1 of these isn't local. Newcastle is the only market where this is usually close to 100% local.
The Sport window is about 4 minutes long, 2 reports and 1 or maybe 2 voiceover items, again in most markets sometimes 1 of these reports and voiceover items won't be local, and Newcastle is the most likely to be fully local.
For News and Sport windows, there are 6 of them, Newcastle (live), Central Coast, Mid North Coast, North West Slopes, Far North Coast and Gold Coast.
In the 'live' section of the bulletin, there is another 2 or so Newcastle items that are aired across Nth NSW and the Gold Coast.
Weather is composite local/national, there's only 4 of these, Newcastle/Central Coast is combined, as is Mid North/Far North, and North West and Gold Coast get their own. It's about 4 minutes.
The other difference is that the local Windows each throw to the ad break, and each of the pre recorded ones use a different music piece, which is like a "extended mix" as its dependent on when the live Newcastle window finishes so they all go to the ad break at the same time. I have seen these pieces run for 30 seconds or more at times.
And oddly, one night I saw the Central Coast window cut off mid report because (for some reason) the Newcastle live window had finished early.
